Which generational gap do you feel was the last big leap in audio?

Gen 7.

This was the first gen where I felt like games were getting closer to cinema. The audio at some cinematic titles like Metal Gear Solid 4 were a huge improvement over gen 6. Full voice acting, high quality music and sound effects...

Gen 8 and 9 improved the quality, but it's getting really hard to notice it.
